Radon Disclosure When Selling a House in Florida
Florida law requires a specific radon gas notice in real estate documents, a requirement many sellers aren't aware of until it comes up in a transaction. Here is what the notice actually requires, and what it doesn't.
Florida's mandatory radon notice requirement
Under Florida Statute 404.056(5), notification about radon gas must be provided on at least one document, form, or application executed at the time of, or prior to, a contract for the sale and purchase of any building, or the execution of a rental agreement for any building. This applies broadly to real estate transactions in Florida; the statute exempts only short-term residential occupancy of 45 days or less. Mold is a separate disclosure and licensing topic worth checking at the same time; see our guide on selling a house with mold in Florida for what that involves.
The exact language the statute requires
F.S. 404.056(5) specifies the required wording precisely: "RADON GAS: Radon is a naturally occurring radioactive gas that, when it has accumulated in a building in sufficient quantities, may present health risks to persons who are exposed to it over time. Levels of radon that exceed federal and state guidelines have been found in buildings in Florida. Additional information regarding radon and radon testing may be obtained from your county health department."
What the notice does not require
F.S. 404.056 is a notice statute, not a testing or disclosure-of-results statute. It does not require a seller to test the property for radon, obtain a radon inspection, or disclose specific radon levels. A buyer who wants radon testing done can arrange it as part of their own due diligence, and any resulting negotiation over remediation is a separate matter from the notice requirement itself, which is satisfied simply by including the required language in the appropriate document.
Where a sale fits
The radon notice requirement applies regardless of how a house is sold, whether listed with an agent or sold directly to a cash buyer, and it does not depend on the property's condition. An as-is cash sale still needs the statutory notice included on the appropriate document at or before the contract is signed, the same as any other Florida sale. This is a separate requirement from the flood disclosure Florida law also requires; see our guide on Florida's flood disclosure law for how that distinct requirement works.
Frequently asked questions
Does Florida require a radon disclosure when selling a house?
Yes. Under F.S. 404.056(5), notification about radon gas must be provided on at least one document, form, or application executed at or before the contract for sale and purchase of any building. This is a general notice requirement, not a requirement to actually test for radon or disclose specific test results.
What does the Florida radon notice actually say?
The statute specifies the exact required language: "RADON GAS: Radon is a naturally occurring radioactive gas that, when it has accumulated in a building in sufficient quantities, may present health risks to persons who are exposed to it over time. Levels of radon that exceed federal and state guidelines have been found in buildings in Florida. Additional information regarding radon and radon testing may be obtained from your county health department."
Does Florida law require radon testing before selling a house?
No. F.S. 404.056 requires the general notice statement in real estate documents; it does not require a seller to test the property for radon or obtain a radon inspection before selling. A buyer may choose to test as part of their own due diligence, but that decision, and any related negotiation, is separate from the statutory notice requirement itself.
Can I sell a house as-is with the radon notice still required?
Yes. The radon notice requirement applies to the sale itself, not to the property's condition or how the sale is structured. An as-is cash sale still needs to include the statutory notice on the appropriate document at or before the contract is signed, the same as any other Florida real estate sale.
